[특징]

기상 연구 및 데이터 분석에 자주 사용되는 엑셀은 논문 및 학술지 발표의 그래프에 많은 시간이 소요
Gnuplot은 명령행 응용 소프트웨어로서 함수와 자료를 기반으로 그래프를 그려주는 도구
과학 기술 분야에서 자주 사용될 뿐만 아니라 Post Script, PNG, GIF SVG, AI 등 다양한 이미지 형식을 지원
특히 Post Script 출력은 매우 강력하기 때문에 Post Script을 기본적으로 지원하는 LaTeX 조화
더 나아가 생성된 그래프를 Adobe Illustrator 등의 벡터 드로잉 프로그램에서 편집하면 더 다양한 표현도 가능

[기능]

stats 통계 변수

변수	내용
STATS_records	범위 내의 자료 수
STATS_invalid	잘못된 데이터 적절하지 않은 자료의 수
STATS_blank	빈 줄 수
STATS_blocks	블록 (빈 줄 두 줄로 구분된다; index로 지정할 수있다)의 수
STATS_outofrange	범위를 벗어난 자료의 수
STATS_columns	자료 열의 수

변수	내용
STATS_mean_x	x 자료의 평균
STATS_stddev_x	x 자료의 표준 편차
STATS_ssd_x	x 자료의 표본 표준 편차 (sample standard deviation; 표준 편차를 계산할 때 N으로 나누는 대신 N-1로 나눈 것)
STATS_skewness_x	x 자료의 비대칭 (skewness)
STATS_kurtosis_x	x 자료의 첨도 (kurtosis)
STATS_adev_x	x 자료의 평균 편차 (average deviation; 평균과의 차이의 절대 값의 평균)
STATS_mean_err_x	x 자료의 평균 오차
STATS_stddev_err_x	x 자료의 표준 편차의 오차
STATS_skewness_err_x	x 자료의 왜곡 정도의 오차
STATS_kurtosis_err_x	x 자료의 첨도의 오차
STATS_sum_x	x 자료의 총합
STATS_sumsq_x	x 자료의 제곱 합
STATS_min_x	x 자료의 최솟값
STATS_max_x	x 자료의 최댓값
STATS_median_x	x 자료의 평균
STATS_lo_quartile_x	x 자료의 아래쪽 분위
STATS_up_quartile_x	x 자료의 상측 분위
STATS_index_min_x	x 자료가 최솟값을받는 자료의 행 수 (예를 들어 10 번째 줄에 x가 최대 값을 가지고 있다면이 변수의 값은 10)
STATS_index_max_x	x 자료의 최댓값을 받는 자료의 행 수

변수	이름
STATS_slope	선형 회귀 곡선의 기울기
STATS_intercept	선형 회귀 곡선의 절편
STATS_slope_err	선형 회귀 곡선의 기울기 오차
STATS_intercept_err	선형 회귀 곡선의 절편의 오차
STATS_correlation	x 와 y의 상관 계수
STATS_sumxy	x * y의 합
STATS_pos_min_y	y가 최솟값을 취할 때의 x 값
STATS_pos_max_y	y가 최댓값을 취할 때의 x 값

프롬프트 상에서 적용

gnuplot> plot [0:3000][] 'fort.888' u 1:(-1*$3)
